This paper studies the 3-dimension active deception jamming instead of the 2-dimension active deception jamming which is invalid for interferometric SAR (InSAR).The 3-dimension active deception jamming need two or more jammers

comparing to that the 2-dimension active deception jamming need only one jammer.This paper studies the error of the 3-dimension active deception jamming.This paper also studies the problem of how to deal with the edge of the active deception jamming image.It is a preferable method to blot out the edge of the images.It can deal with the problem of smooth join of the deception image and the real image.
